Application tiled March 27, 1911. Serial o. 617,242.

To all whom it may concern:

Be it known that l, ARNOLD A. WEIcnL, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements inAntifriction-Bearings; and I do hereby declare that the fol lowing is afull, clear, and exact description thereof, reference being had to theaccompanying drawings','andto the letters of reference marked thereon,which form a pai-tof this specification.

This invention relates to antifriction bearings, and more particularlyto what are known as side bearings for use on railroad cars.

The invention consists of the matters'hereinafter described, 4and. moreparticularly pointed out in the appended claims.

In the drawings :-Figure l is a view representing a longitudinal,central section through a side .hearing made in accordance with myinvention.- Fig. 2 is a bottom plan 'View of the same.` Fig. 3 is an endelevation.

Fig. 4 is a transverse section through the bearing onthe line 4-4 .ofFig. 1. Fig. 5 isV a transverse section through the bearing on line 5-5of Fig. 1. Fig. 6 is a top plan View of the bearing. Fig. 7 is atransverse section bthrough the antifriction rollerand the framesupporting the same showing a slightly modified form of theconstruction.

Referring now more particularly in detail 5 L to the drawings, 10 reresents a casing by means of which the antlfriction device is secured tothe car bolster, said casing inclosing an antifriction roller 11 whichis adapted to transmit load in a familiar manner from a hearing orwear-plate supported in the casing to be more particularly referred tolater, and a hearing or wear-plate 'provided on the truck holster. Thecasing 10 is of oblong, rectangular form and is provided at its fourcorners with ears 12 located on a level withits top surface land hvmeans pf which it is adapted to be secured to the car bolster by bolts(not shown) which pass through, apertures 12EL in said ears. The saidcasing comprises side members 13, 13 and end members 14, 14. Thelatterare pro-` vided 'on their inner faces with transverselyl extending lugsor shoulders 15, 15 on whic rests a bearing or'wear-plate' 16, saidwearcasing 10; Said ribs or flanges 18, 18, of the filler block 17,depend below the lower face of the wear-plate 16 and provide thrustshoulders to take up the lateral thrust of the antifriction roller 1 1.y

The antifriction roller 11 is sus ended from the frame or casing 10 bythe ollowing mechanism: 19 indicates a roller frame comprising laterallyspaced side members 20, 20, and transverse webs 2l, 21 which are locatedonein front and one at the rear of the roller 11. The side members 20,2O of said roller bearing 'frame are connected at their ends bytransverse rods 22, 22 which extend through vertically elongatedapertures 23, 23 formed in sleeves 24, 24 which are each made integralwith a pair of upright links 25, 25. 1Said links and sleeves togetherconstitute swinging suspension members 24a which conne'ctthe rollerframe with the casing and suspend the said roller frame therefrom. Atthe upper ends of said links 25, 25 are formed vertically elongated eyes26, 26 by means of which sald links are suspended from transverse rods27, 27 secured to the frame 10.

As shownV in Figs. 1 to 6, inclusive, the antifriction roller 11 isprovided with integral trunnions 28, 28 which rest in U-sha ed, upwardlyopening sockets 29, 29 formed in the side nim'hers 20, 20 of the rollercarrying frame.

The operation of the bearing is as fol lows: lVhen the roller istransmittino' load and'engaged with the bearing or wear-plate 16, therods 22, 22 are in the highest parts of the apertures through which theyextend, and the-links `25 'are each, as a whole, in their -highestposition with the rods 27 in the lowest parts of the eyes 26 in saidlinks in which they are located. When the antifriction roller rolls awayfrom the center ,of the casing it carries the roller.bearing weight ofthe suspension members 24a, 24a comprised by the pairs of links 25, 25and the associated integral sleeves 24,24 causes them pendulum-like toswing toward a vertical position, thus returning the roller bearingframe to its normal central position and with it the ant-ifrictionroller.

In the preferred form of my improved bearing the rods 27 are mounted inthe frame so as to be non-rotative, said rods being squared at one endas shown'in Fig. 5. The links 25 are each provided with a detent 26adepending from the upper side of the eye 26and adapted to engage inanotch or opening 27a 'in the rod 27, below said detent. The object ofthese detents and notches is as follows: After the roller carryingtrame, during the transmission of load by the r roller, has moved to oneor the other side of the center ofthe frame or casing and when theroller is released and brought back to center by means of the swinging,suspension members 24a, the detents 26a of the links engage in thenotches 27a of the rods 27 and lock said suspension members in verticalposition. This position is maintained, notwithstanding jars or liolts ofthe car until l the antitriction roller is raised into engagement withthe wear plate 16, when said roller is next brought into place totransmit load from the body bolster to the truck bolster. This preventsla constant swinging movement of the suspension arms when theantifriction member is idle and obviates the resultant wear and rattlingof the parts.

In Fig. 7 I have shown a modification of the means by which thegrolleris supported in its frame. In this case 11a indicates the roller," and20a, 20a the side members of its supporting frame. 'The roller 11a has acentral bore 30 in which is located a bolt or rivet 31 which extendsthrough suitable apertures 29a, 29El formed in the side members ofthe'frame, said bolt being held in place on one sideby a head 32 and onthe other by a nut 33. In this case, the roller "instead ofhaving'integral trunnions which have bearing in the side members of theframe is journaled on a bolt which rigidly connects the 'side members ofthe frame. Manifestly, the bolt might be replaced by a rivet.

I claim as my invention 1. In a'n antifriction bearing, in combinationwith an antifriction member, and a swinging suspension member adaptedfor supporting said antifriction member, means for locking said swingingsuspension member ina predetermined position when said antifrictionmember is not transmitting load.
